The Snyder Industries 550 Gallon ASTM Black Heavy Duty Vertical Storage Tank is a polyethylene vertical storage tank built for bulk water and weighted-content service. It stands 46 inches tall on a 64 x 64 inch footprint, so a full 550 gallons sits low and wide rather than tall and tippy. That squat geometry keeps the center of gravity down, which matters when you are staging a black vertical tank outdoors on a pad or in a truck bed.
Will it work for your site?
Two numbers drive the sizing decision. Filled with plain water this tank carries roughly 4,587 pounds of contents. At its 1.9 specific gravity rating it is built to hold up to 8,715 pounds — and that higher number is the one that matters. Size your pad, your bed, and any secondary containment to the 8,715 lb loaded figure, not to the water weight. The 1.9 SG rating is the reason this is called a heavy duty tank: the wall carries contents far denser than water, so you have real structural margin for weighted or mineral-laden water rather than running the shell at its limit. If you are unsure how 550 gallons maps to your draw-down and refill cycle, run the numbers through our Tank Sizing Calculator or read the Tank Sizing Guide before you commit to a footprint. If you are filling with a denser or thermally active fluid, our guide on freeboard sizing per ASTM D1998 covers the usable volume you actually get once you leave headroom.
Pad, footprint, and the mistake to avoid
The 64 x 64 inch footprint needs a flat, fully supported base — a vertical storage tank at over 8,700 pounds loaded is not something to set on gravel or a partial pad. Support the entire bottom on a level, load-rated surface. For above-ground concrete work, our guide on concrete pad sizing for above-ground polyethylene tanks walks through the ACI framework. The common mistake is treating the black color as a chemical rating — it is not. This tank is classed for water and general bulk storage; the 1.9 SG rating is a structural margin for weighted or mineral-laden water, not a chemical-compatibility listing. Match any specific chemical to a chemical-rated tank and confirm the fitting and gasket material separately.
Fittings and outlet
Outlet and bulkhead fittings on this listing are configured at order rather than fixed as a spec, so before you buy, call 866-418-1777 to confirm outlet size, placement, and gasket material for your plumbing. It is a five-minute conversation that saves a return trip to the hardware store on install day.
